Import Tips

• Include UV absorption spectra verifying provitamin structure; animal-derived forms need BSE/TSE certification

• Document solvent use per Chapter 29 note (e) if dissolved; stabilizer additions must be for transport only

• Avoid 'vitamin D3' labeling to prevent premature classification; specify photo-conversion required
